Step Drills

Step drills are versatile multi-diameter drilling tools designed for creating, enlarging and sizing holes in sheet metal, plastics and thin materials. Manufactured from high speed steel (HSS), they allow multiple hole sizes to be drilled using a single tool, reducing the need for frequent bit changes and making them ideal for fabrication, engineering, electrical installation and maintenance applications.

Available in size ranges including 4–12mm, 4–20mm, 4–30mm and 4–39mm, step drills provide clean, accurate holes with reduced burr formation and excellent control. Suitable for drilling new holes or enlarging existing ones, they deliver reliable cutting performance, long service life and professional results across a wide range of materials.
